Improving nutritional quality of wheat through soil and foliar zinc application

A field study was conducted to ascertain the effect of three zinc (Zn) levels: 0, 20 kg ZnSO4/ha and 20 kg ZnSO4/ha + foliar spray of 0.5% ZnSO4, on wheat grain Zn content and factors contributing to or hindering in its bioavailability. Increasing Zn levels were established as serviceable in improvi...

Zusammenfassung:	A field study was conducted to ascertain the effect of three zinc (Zn) levels: 0, 20 kg ZnSO4/ha and 20 kg ZnSO4/ha + foliar spray of 0.5% ZnSO4, on wheat grain Zn content and factors contributing to or hindering in its bioavailability. Increasing Zn levels were established as serviceable in improving the nutritional status of genotypes. Soil application + foliar spray proved to be paramount for all the traits leading to an 80% increase in grain Zn content, 61.3% in methionine content and a decrease of 23.2% in phytic acid as an average of all genotypes and both years. The genotype UP 2382 was found more suited to Zn fertilization in allocating Zn and maintaining a lower phytate to Zn molar ratio.
